Could bad plugs or coils also cause very small rpm fluctuation ?? On a right budget could really use some help with my 2010 Chevy Silverado no codes no lights besides tire pressure monitoring system I just had to change my u joints one was pretty seized up I'm hoping it didn't cause further problems but iv had the truck 3 years n haven't had a tune up yet

[@DonNeil4]

Did your car have a jerking symptom when at idle or acceleration?

[@DPLS77]

My 6 plugs looked like the one at the beginning. I had loss of power and rough idle symptoms, so today I had my spark plugs changed and the difference is noticeable. My car doesn't have a rough start anymore, cold start idling is stable, and acceleration is smooth. Hopefully it fixes my MPG issue as well, fingers crossed. Thanks for the help!

@@victorlafranceya I would say change your spark plugs and start with that Engine codes can mean a lot of things and my dodge charger came up with a an issue with the “short runner valve sensor” so I replaced them and still check engine light… but I’ve been avoiding changing the spark plugs because it’s a lot of work… I ended up doing it and my plugs were toasted. Rusted, no tip of spark and a huge gap in between the plugs…. Video explained symptoms of bad spark plugs and it’s all true. Lost of power, bad gas mileage and takes a few seconds longer to start… After spark plugs, car turns on right away no hesitation… car has full power now and def no more check engine light

The majority of the symptoms you have said in this video is what my car is doing.

I have the same issue on my opel insignia 2.8 v6. Drives perfectly fine even on high speed of around 250kmh as long as i don lt push the car and change gears quickly. As sson as i press the gas fully and accelerate the check light blinks for 4 to 5 seconds and car starts to vibrate and can feel jerking on gas till i turn off the car and when turn it back on its normal again.

Im having a hard time finding an answer to this but my vehicle runs like crap after I start it if it has been sitting for longer than a half day. Bogs down under acceleration, sputters and chokes, it does this until it warms up then runs perfectly fine. My hunch is that it is the plugs, what do you think?

Work for a dealership, and the techs told me it may also be a bad fuel pump not sending proper fuel pressure. (Didn’t physically see my car but just gave me another example to what could be causing my issue)

I bought second hand Skoda Rapid 1.0 tsi 81kW, on the sale 37k mileage. Not bad, right? But soon after it started to quake on 1.5-2k revs half gas or more. Wtf?

[@peterblumer9910]

You missed an important diagnoises If you take an ohm meter and test thr Plug what happens is the meter will read anywere from 1800 to 3100 ohms hopwever the plug can not maintain proper ohm the meter will fluciate from ohms to open. if the plug is bad on the inside, I have bought new plugs and found at least 1 that were probably dropped and the plug was bad. the engine will intermittantly stop firing creating the misfire. this was verified on several ford f120 250 and 350 engines.

Sounds strange but German plugs are good for German cars. 🏯 Japanese plugs are good for rice burners. That's from over half a century of my experience. Always multimeter check for continuity and impedence isolation from center and insulator before installing ( manufacturers fired quality control employees to gives stockholders an extra nickel).
